Optional dependencies

iso-codes (>= 3.67) is needed for displaying language and region names.

For Mobipocket (.mobi) and Kindle File Format (.azw, .azw3) support, you would need Python (2.7 or >= 3.4).

Auto-hyphenation is done using CSS hyphenation. To enable CSS hyphenation in WebKitGTK, you will need to install the hyphenation rules, e.g., hyphen-en for English, hyphen-fr for French, etc.

For offline dictionary support, install dictd or sdcv.

For text-to-speech support, install espeak-ng, or festival, and packages for the individual voices.

To enable spellchecking for notes, gspell (gir1.2-gspell-1 for Debian based distributions) is requried.

libhandy (gir1.2-handy-0.0) is recommended to make the interface work better on larger as well as smaller screens.

If tracker (gir1.2-tracker-2.0) is installed, it can be used to track the locations of files.
